Subject: [PATCH 0/3] nvmem: stm32: add OP-TEE support for STM32MP13x
Date: Fri, 28 Oct 2022 16:52:48 +0200 [thread overview]
Message-ID: <20221028145252.2115933-1-patrick.delaunay@foss.st.com> (raw)
This serie update the NVMEM BSEC driver to be compatible with STM32MP13x
SoC and the trusted application STM32MP BSEC in OP-TEE
This serie solve issue in initial support of STM32MP131
(using BSEC STM32MP15 compatible) and so it break the DTS compatible.
I create this serie for more efficient review.
The 2 first patches of this series are re-sent of patches already sent
1- "dt-bindings: nvmem: add new stm32mp13 compatible for stm32-romem"
https://lore.kernel.org/all/20221014172324.1.Ifc1812116ff63f5501f3edd155d3cf5c0ecc846c@changeid/
https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=685403
2- "ARM: dts: stm32mp13: fix compatible for BSEC"
https://lore.kernel.org/all/20221017134437.1.I167a5efc1f8777cce14518c6fa38400ac684de3e@changeid/
https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=685815
This DTS break is acceptable as
- the STM32MP13x SoC is not yet available outside STMicroelectronics
(not official)
- the same patch is already integrated or modifications are in progress in
the other users (arm-trusted-firmware/TF-A, OP-TEE and U-Boot) of
stm32mp131 device tree.
It is the good time to correct this issue before the real availability of
the SoC and before full support of SoC in Linux kernel.
This last patch on NVMEM STM32 ROMEM driver in depend on the preliminary
patch for the driver:
"nvmem: stm32: move STM32MP15_BSEC_NUM_LOWER in config"
https://lore.kernel.org/all/20221017174953.v2.1.I95e71328dd654723bd4c57206bd008ff81c726bb@changeid/
present in the serie
"nvmem: stm32: several minor improvements"
https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=685886

Patrick
Changes in v1:
- update commit message to indicate DTS break reason.
